SAFETY RAZOR.

Application flledlugust 18, 1925, Serial No. 51,010, and in Austria l 'ovember 10, 1924.

This invention relates to a safety razor in which a substantially flat blade is mounted between a bed plate and a cover plate. The principal objects which the present invention has in view are: to provide such con necting means between the bed plate of the safety razor and itsjhandle, that the latter may be adjusted quickl at any desired angle relatively to the bed p ate and consequently to thecutting edges of the razor blade, further an improved device for easily ejectmg the blade and a special form of the guard device.

Several embodimentsof the invention are shown in the accompanying drawings in which- I Fig. 1 represents in sideview partly in section a safety razor with one form of the connection between the handle and the bed.

cover-plate is grooved as to form three ledges 5, 6 and 7. From one to the other narrow side of the bed-plate are running two ledges Y 8, 8' between which pins 9, 10. are inserted to engage corresponding holes of the blade 11. On the narrow side, of the bed plate opposite to the hinge 3 a tongue. 12 is hinged at 13, which extends below the razor blade and lies flush in the bed plate. The tongue 12 carries an outwardly projecting finger 14, whereas on thefree narrow side of the cover plate a locking member 15 is hinged. To makethe safety razor ready for use, the

blade 11 is put upon the bed plate (Fig. 3),.

then the cover plate is turned down in the position, shown in Fig. 3 by dotted lines and the locking member 15 is pulled over the finger 14, in the direction o fthe arrow p, a

pressing thereby bed plate.

In order to remove the blade,,first the locking member and then the cover plate is turned up. Now a light pressure upon the the coverplate against the.

edges with little protuberances 18' in comblike intervals with the effect, that the apparatus during the use adheres with a full edge to the skin and not with the separate teeth of the comb, whereby a uniform tension of the skin is secured. Further the hole cutting edge of the blade becomes operative and the hairs are directed towards 'the cutting edge by the above mentioned protuberances.

On the ends 19, 20 of the bifurcated springy handle 21 hemispheres 22, 23 are formed, the bases of which are provided with radial grooves 24 as shownby Fig. 7, 8. The cross section of these grooves corresponds .to the polygonal cross section of a mandril 25, fixed on the underside of the bed plate.

In the drawingsa square mandril is represented, but the lnvention is not limited to this form of cross section. Each pair of "grooves may surround and hold fast the mandril by the spring force of the bifurcated handle. The mandril is also provided with two pins 26, 27 engaging corresponding holes 28, 29 in the two hemispheres 22, 23. These pins act as pivots when the mandril is turned from one groove to the next and prevent simultaneously the mandril from slipping out of the handle.

Accordingto F1gs.5 and 6 the mandril is fixed obliquely on the bed plate and according to Fig. 5 provided with pins 26-, 27 en aging corresponding holes in the hemisp eres 22,2301 as illustrated by. Fig. 6 a ball 30 is formed on the mandril engaging hemispherical recesses 31, 32 in the 'two hemispheres of the handle. By this oblique arrangement of the mandril the bed plate together with the razor blade may be adjusted by turning the mandril in such a position, that the bed plate and the handle venient position for commodious shaving.-

By the arrangement of a ball on the man-,

dril engaging ball shaped recesses in the hemispherical ends of the handle a double movement of the bed plate 1 with-respect to the handle is possible. Inthe first bed plate may be adjusted oblique y to the place the handle or turned down by turning the mandril from one pair of opposite grooves of the hemispheres, 2:2, 23 to the other, whereby the ball serves as a pivot. Further it is possible to rotate the mandril together with the bed plate in the bearing formed by a determined pair of opposite grooves;

By this latter arrangement it is possible to adjust the cutting edge of the razor blade at any convenient and desired position rela tively to the handle, which is held in the hand.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. In a. safety razor an arrangement for adjusting the handle with respect to the bed plate carrying the blade, comprising a mandril of polygonal cross-section secured to the underside of the bed plate, a bifurcated springy handle, hemispheres on the ends of the latter, grooves adapted to the cross-section of the mandril in the base of each hemisphere, one pair of grooves surrounding and holding the mandril in the desired position when the safetyrazor is in the desired operative position.

2. in a safety razor an arrangement for adjusting the handle with respect to the bed plate carrying the blade, comprising a mandril of polygonal cross-section secured to the underside of the bed plate, a bifurcated springy handle, hen'iispht-res on the ends of the latter, grooves adapted to the eross-section of the mandril in the base of each hemisphere, recesses in the two hemispherical ends of the handle, and extensions on the m'andril for engaging the said recesms to prevent the mandril from slipping out of the handle when moving from one groove to another groove.

3. In a safety razor an arrangement for adjusting the handle with respect to the bed plate carrying the blade, comprising a mandril of polygonal cross-section secured at an angle to the underside of the bed plate, a bifurcated springy handle, hemispheres on the ends of the latter, grooves adapted to the cross-section of the mandril radially disposed in the base of each hemisphere, one pair of grooves surrounding and holding the mandril in the desired position when the safety razor is in the desired operative po- 'sition.

4. In a safety razor an arrangement for adjusting the handle with respect to the bed plate carrying the blade, comprising a mandril of polygonal cross-section secured at at angle to the underside of the bed plate, a bifurcated springy handle, hemispheres on the ends of the latter, rooves adapted to the cross-section of the mandril radially disposed in the base of each hemisphere, recesses in the two hemispherical ends of the handle, and extensions on the mandril for engaging the said recesses to prevent the mandril from slipping out of the handle when moving from one groove to another groove.

In testimony whereof I have signed my name to this specification.
